Magnetic instrumentation and other applications of magnets in NOTES.

Modern surgery is developing towards a minimally invasive approach. To minimize the trauma the number of ports is either limited as in single incision laparoscopic procedures or ports are introduced through natural orifices as in natural orifice translumenal endoscopic surgery (NOTES). To provide surgeons with appropriate instrumentation novel technologies are employed involving magnets.

Transvaginal NOTES cholecystectomy in my partner? No way!

Introduction: Natural orifice transluminal endoscopic surgery (NOTES) transvaginal cholecystectomy is being intensively studied. A few studies have been recently published evaluating patients' attitude towards NOTES with its individual accesses. However, the choice of a transvaginal access with its potential influence on sex life and fertility is not restricted entirely to women.

Surgical morphology of the pancreatic isthmus.

Background: Pancreatic isthmus method anastomosis following pancreatic resection is an important factor of postoperative fistula formation. While the anatomy and vascular supply of the pancreatic head have been studied in detail, little is known about the morphology of the pancreatic isthmus. The authors determine the anatomy and morphology of the pancreatic isthmus.

An unusual presentation of pancreatic pseudocyst mimicking cystic neoplasm of the pancreas: a case report.

In spite of their rarity, cystic neoplasms of the pancreas are characterized by existing or potential malignancy that cannot be ignored during decisive process with regard to the choice of treatment. Diagnostic difficulties in the differentiation of pancreatic pseudocyst and cystic pancreatic neoplasm can lead to misdiagnosis and inappropriate treatment, since clinical symptoms, preoperative imaging tests and even endoscopic retrograde cholangiopancreatography are often not sufficient to establish the correct diagnosis. We present a case of pancreatic cyst with no typical features of pseudocyst in the medical interview, treated by Child's subtotal pancreatectomy by reason of the high risk of neoplasia suggested by radiological and endoscopic examinations.

Pancreatic duct diversity.

Objectives: The formation of the pancreatic duct system is the result of the fusion of 2 embryonic buds, the ventral and dorsal primordia. Frequently, this fusion process is localized in the pancreatic head; variations, however, may account for the structural diversity of the duct system. Pancreatic duct anomalies and diversity of body and tail are thought to be casuistic.

Changes in glucose metabolism after Kausch-Whipple pancreatectomy in pancreatic cancer and chronic pancreatitis patients.

Objective: Although changes in exocrine pancreatic function after pancreatoduodenectomy (PD) have been thoroughly analyzed in many reports, articles concerning endocrine have been few. An investigation of glucose metabolism changes in patients undergoing PD was performed.

Methods: In the study, 20 patients were subjected to pancreatic head resection for tumorous lesions (13 neoplasmatic and 7 chronic pancreatitis) and followed-up for changes in pancreatic endocrine function.

Biliary versus alcohol-related infected pancreatic necrosis: similarities and differences in the follow-up.

Objectives: Infected pancreatic necrosis (IPN) is a serious complication of acute pancreatitis. Data concerning survivors' quality of life and pancreatic functions are scarce. Follow-up of the patients with alcohol and biliary etiology of IPN treated with open necrosectomy was performed.

Prospective evaluation of the defecatory functional results in patients following aorto-aortic reconstruction surgery for an abdominal aortic aneurysm.

Purpose: Anterior rectal resections have been associated with postoperative bowel function abnormalities, a condition defined as anterior resection syndrome. Autonomic denervation could be one of the possible mechanisms underlying this complication. Damage to the preaortic tissue containing autonomic nervous plexus during abdominal aortic reconstruction surgery may affect the anorectal defecation function.

Blood supply of colorectal polyps correlates with risk of bleeding after colonoscopic polypectomy.

Background: The most common complication of endoscopic polypectomy is hemorrhage. Several factors have been reported to increase the risk of hemorrhage after polypectomy, but controversies still exist. Additionally, the pathomechanism of this complication is not well understood.

Heparin improves organ microcirculatory disturbances in caerulein-induced acute pancreatitis in rats.

Aim: Microcirculatory disturbances are important early pathophysiological events in various organs during acute pancreatitis. The aim of the study was to evaluate changes in microperfusion of the pancreas, liver, kidney, stomach, colon, skeletal muscle, and to investigate the influence of heparin on the organ microcirculation in caerulein-induced experimental acute pancreatitis.

Methods: Acute pancreatitis was induced by 4 intraperitoneal injections of caerulein (Cn) (15 microg/kg).

[Endoscopic dilatation of benign gastrointestinal anastomotic stenosis with hydraulic balloon].

Incidence of postoperative anastomotic stenosis range from 5 to 30 percent though most of them are not clinically relevant. Strictures of gastrointestinal tract (GI) within reach of the endoscope may be treated successfully with dilatation. The aim of the study was to evaluate the technique of endoscopic balloon dilatation in the treatment of GI anastomotic strictures.
